Google Detect Wrong Product Price

I use Google Merchant center to submit product feed and product information for Google shopping advertisements.

I submit products in different currencies with your tool. But lately, Google has continuously detected errors in the product price. For example, the product price with your tool should be ￡21.24 but it turns out Google has crawled the original price in USD $24.99.

Even though I myself load the page and the product price is the right one ( which should be GBP), but I need your help to find out why Google has continuously detected the original price not the converted price in GBP?

This is urgent for me, IF you have checked this topic, please reply.
